COLLISION AVOIDANCE SYSTEM BY ADAPTIVE CRUISE CONTROL
[attachment=29425]
INTRODUCTION
FAST..FASTER.…FASTEST the only adjectives which are ruling our lives now.
This theory is applicable for all the different aspects of life. And so it even includes fast driving and riding as well
DRIVER ASSISTANCE SYSTEM
Driver Assistance Systems are systems to help the driver in its driver process.
Designed with a safe Human-Machine Interface ,increases vehicle safety and more generally road safety.
ADAPTIVE CRUISE CONTROL
Adaptive Cruise Control systems automatically adjust a car’s speed to maintain a safe following distance with preceding vehicle.
It uses automatic transmission system that uses forward – looking radar.
COMPONENTS
1.MILLIMETER WAVE RADAR
2.DIGITAL SIGNAL PROCESSOR
3.STEREO CAMERA
4.IMAGE PROCESSOR
5.HEAD WAY CONTROL UNIT
6. LINKS WITH POWER TRAIN
PHASED ARRAY RADAR
A group of antennas.
The relative phases of the respective signals feeding the antennas are varied.
Radiation pattern is reinforced in a desired direction.
Suppressed in undesired directions.
The radar beam is electronically steered.
It can direct radar beams fast enough to maintain spy on many vehicles simultaneously coming in different directions.
FEATURES OF ACC
Capable of recognizing forward traffic regardless of rain or other inclement weather conditions.
Provides smooth deceleration comparable to that ordinarily obtained when the driver decelerates the vehicle.
CONCLUSION
One of the potential advantages of ACC is
the foundation it provides for the next
generation advancements in intelligent
transport systems.
It’s the beginning of microwave era in
automotive electronics.
